What is “__name__” and “__main__” in Python? A guide to unravel the mystery behind the Python code of __name__ and __main__

What does this line of code mean?

if name == “main”:

The whole idea behind this line of code is that when you are importing from a module, you would like to know whether a module’s function is being used as an import or if you are using the original “.py” file of that module. In such cases, we use the above line.

When your script is run by passing it as a command to the Python interpreter:

python myscript.py

all of the code that is at indentation level 0 gets executed. Functions and classes that are defined are defined but none of their code gets ran. Unlike other languages, there’s no main() function that gets run automatically- the main() function is implicitly all the code at the top level.
